I have Window 8 Installed, I can't install Windows 7 first
My question is not that, I need to know if is possible and supported these options:
Windows 8 is installed on PC
A) Create a VHD on PC, install Window 7 on it and create a dual boot
B) Create a VHD on USB, install Window 7 on it and create a dual boot
C) Install Windows 7 directly on USB
Notes:
Support Policy for Windows booting from external drives
